Hello,

We have a sprayed that gets a 24 volt signal. What’s a cheap way we can modulate that signals duty cycle.
My initial thought is a programmable relay and some sort of analog dial.

Suggestions appreciated.

 

Please explain what your particular 24V signal is.
A binary discrete signal, meaning 0V or 24V?
Or a pulse width modulated signal; a binary discrete signal whose on/off periods vary in width?
Or a continuously modulated 0-24Vdc signal?
Or something else?

 

What is the input impedance of the sprayer input?

 

Omron has nice reliable timer relays

I’m mystified why if it is a sprayer, one would want to modulate anything connected with it.
Am I missing something ?!
